    I've used one of those PSU's in one of my past installs. It's a nice PSU.. Thing is, for this scenario, all we need is regulated power.. That seems like overkill because the board already has the PSU, it just needs regulated 12V, right? So, I wouldn't think that is the *cheapest* working solution..

    Please correct me if I'm wrong.

    Thanks

    You need regulated 12v and you probably want some integration with the ignition so it will startup and shut down with the car. If budget is your biggest concern I guess you could use a very low cost inverter brick and a 120v ~5-6 amp wall brick. That would not give you ignition integration.

    Cheap inverters also are known to inject noise into systems.

    You could probably also hack together the atx connector on a m2-atx, but that is again a hack.

    Maybe some of the forum members have other ideas.

    mini box came up with the solution for powering these:

    http://www.mini-box.com/DCDC-USB

    however they have yet to make them work with their pico-UPS which is just stupid.
    Ideally I'd like a small SLA battery provide ups power the rig as ups after the main batt is down to say 11.2V and have just ONE power supply that can connect to the ups and be aware of both batteries so it could switch over

    Power Consumption / Battery Life

    My informal testing revealed that with the following setup:

    D945GSEJT
    1024x768 resolution
    40mm case fan, speed set on low in BIOS
    2GB RAM
    160GB 5400RPM HD
    USB 802.11n card (on)
    USB Bluetooth adapter (on)
    Creative Labs Sound Blaster Audigy 4 PCI sound card with kx project driver, 1 insertion delay and reverb effect
    CPU at approximately 40% load playing video on VLC media player

    ... yields about 30 minute run time on a fully charged 12V 2.3AH SLA (Gel cell) battery.

    The board shut down occurred at approximately 7.5V.

    Thats good right? So are you happy with this board? I am trying to setup mine in a way that it uses very little power. Only thing it will have is 2GB Ram, 40GB HDD, and thats it. The keyboard and touchscreen are powered by the KVMP switches. How many amps is your setup using?

    It is pretty good. The number is almost comparable to a netbook; it should be no surprise since the 945GSE chipset is a notebook chipset.
    The sound blaster card alone pulls about 0.4A (4.8W)

    Here is an older test I did with a 320GB 7200RPM notebook HDD:

    Standby (Off): 0.04A (0.48W)
    On (CPU idle): 1.03A (12.36W)
    On (CPU full load): 1.56A (18.72W)

    The numbers quoted above consists of purely the computer itself without display or amplifiers. I plan to use the 12v 1.2AH SLA battery to provide temporary power during shutdown / hibernate when the engine is turned off. Power status will be reported to a serial port and the XP's built in UPS software will provide the hibernate / shutdown function.

    And what about native for Lilliputs 800x480 resolution?
    Is it possible with this board? (VGA or DVI)

    I try to set 800x480 (VGA) on Asus EEE 901 (same chipset) by Intal drivers modify DTD string, but Lilliput controller reconize it as 640x480 and, of course, picture was very poor.

    What about D945GSEJT?

    Thanks.

    Very pleased so far with this mainboard, but bit frustrated as the supplied SATA power cable has a 1 x SATA and 1 x 4-pin Molex outputs, which means you need another cable to add a second SATA drive

    Anyone know where I can get a cable with 4-pin Molex female to 2 x SATA?

    Also, where might I get a connector for the on-board SPDIF?

    thanks

    Are you talking about a Y-Cable? http://www.amazon.com/SATA-Power-Y-C.../dp/B000ZD56QK This one is from Amazon.

    I got native 800x480 resolution to work using a modified driver found in one of the older 945 threads. My 2010 Lilliput EBY701 shows it as 800x480 55Hz.
